TERMINOLOGY FOR NIBP
Oscillometry
The oscillometric method of blood pressure measurement is a non-invasive method that
monitors the amplitude of cuff pressure changes during cuff deflation to determine arterial
blood pressure. The cuff pressure is first elevated above the patient systolic blood pressure
level and the cuff begins to deflate at a certain rate. The initial rise in amplitude of these
pressure fluctuations during cuff deflation corresponds closely to the systolic blood pressure.
As the cuff is further deflated, these pressure fluctuations increase in amplitude until a peak is
reached which is usually referred to as the mean arterial pressure(MAP). As cuff deflation
continues, the diastolic pressure can be determined based upon the rapidly diminishing
amplitude of the pressure fluctuations. Thus systolic, MAP and diastolic blood pressures can be
accurately obtained by supervising the pressure fluctuations while controlling the cuff deflation
rate.
mmHg
Millimeters of Mercury, which is the most common unit of measure for pressure in non-invasive
blood pressure.
NIBP
Non-invasive blood pressure.
bpm
Beats per minute, which is the most common unit of measure for pulse rate.
Advantage OEM NIBP Technology Series
Term encompassing all of the Advantage OEM NIBP technologies and module platforms.
Patient Populations
There are three major patient groups which are formally defined as neonate (up to 28 days),
pediatric (29 days to 12 years) and adult (13 years and older).
